Once I wanted to make a photo frame for a friend. There are so many ways to do this, but then I got an idea I still find great ;-))
I used a simple glass frame as seen on the second photo that I already had at home and glued a kind of Paper Crazy Quilt with two windows for the photos onto the glass.
I used flower photos from an ad as paper and the only embroidery stitches I used where the zigzag stitches, because I wanted it to be simple.
